Question

ALTER TABLE TableName 添加FULLTEXT INDEX IndexName（ColumnName）;

这是在mysql中添加全文索引的查询。

但是，我想要添加全文索引的laravel查询。

提前感谢......

Answer 1

应该这样做：DB::statement

DB::statement('ALTER TABLE TableName ADD FULLTEXT INDEX IndexName (ColumnName)');

Answer 2

在Laravel> = 6.15.0上，您可以像这样扩展Illuminate\Database\Schema\Grammars\MySqlGrammar和Illuminate\Database\Schema\Blueprint类（例如，在boot()的{{1}}方法上）：

AppServiceProvider

并在您的迁移中像这样使用它：

use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Schema\Grammars\MySqlGrammar;
use Illuminate\Support\Fluent;

Blueprint::macro('fulltext', function ($columns, $name = null, $algorithm = null)
{
    return $this->indexCommand('fulltext', $columns, $name, $algorithm);
});

Blueprint::macro('dropFulltext', function ($index)
{
    return $this->dropIndexCommand('dropIndex', 'fulltext', $index);
});

MySqlGrammar::macro('compileFulltext', function (Blueprint $blueprint, Fluent $command)
{
    return $this->compileKey($blueprint, $command, 'fulltext');
});

对于多个Columns/Fields

DB::statement('ALTER TABLE Database.TableName ADD FULLTEXT fulltext_index (Col_1, col_2, col_3)');
